Good quality Carbon Fiber Chemical Pump for sales

The pump works well. Wish more online training after more great products.

—— Mr. Artem Kazmirchuk

Yongyi does really good on the design and manufacturing of the products. the engineers is professional and the service is good.

—— Efim Nehoroshkov

I read the reviews and decided on this model. After using this powered pump, I was so happy with my decision. I was incredibly impressed with this pump. So far it's been working great.

—— Sally

Powerful pump. Easy to use and a very reasonable price. What else can you ask for. So far so good we will see how this pump will perform in the long haul.I do wish it had come with a output hose though.

—— Galo Cevallos

Wow, much higher quality and materials than I expected. Worked great to transfer sulfuric acid. Great pump for the price.

Electrical Open Impeller Industrial Chemical Pumps / Volute Centrifugal Pump

Working Principle

The centrifugal pump working principle is as following:

1. Through a suction flange the liquid flows through the suction hub into the rotating impeller.

2. The pump shaft absorbs mechanical energy from electric motor,and turn the electric energy into mechanical energy.

3. The blades fixed on the shaft exert a force on the fluid and increase its angular moment, so the pressure and absolute speed increase.

4. Consequently energy is being transferred to the fluid.

Features

WD series anti-corrosion and wear-resistant horizontal centrifugal pump adopts the current general structure: bracket support and rear door form, which make the pump disassembly and maintenance safe and convenient, and the maintenance and repair cost is low.
WD series pump adopts integral casting impeller. The pump body adopts wide flow channel design, which makes the pump adaptable to the working conditions and has strong pump passing ability. It is especially suitable for high solid content, high viscosity and easy crystallization medium. It has high efficiency and excellent anti-cavitation performance.
The bearing body adopts an axially movable structural design, which can adjust the axial clearance between the auxiliary impeller and the packing chamber without disassembling the pump.
